    i have a ATV and love it, but have recently been watching some blu-ray movies and admit they are amazing, so my question is this: how much of a difference is the HD ATV movies vs the PS3 blu-ray movies?

    thanks!

    Well if your TV supports it, its

    720p(ATV) vs 1080p Blue Ray disk

    Also depends on how you connect that devices

    It will also depend on your screen (plasma/LCD/projector). If your screen is 1080 native then you will see a difference. If it is only 720 native then the 1080 will be scaled to your screen and the visible difference will be marginal.

    Here in the UK the first HD screen were only 720 native (extended definition?) and not 1080 native. Now more 1080 native screen are on the market and I am getting upgraditis!

    Blu-Ray will be virtually uncompressed 1080 video (that's why they hold 50 gigs or so) and likely have uncompressed audio (True HD).

    The ATV will have H.264 720 compressed video (highly efficient, but compressed nonetheless) and, at best, Dolby Digital (compressed 5.1) audio.

    Wouldn't uncompressed 1080p be the following:
    (24fps) x (1920 x 1080 pixels) x (24bit color)= 1,194,393,600 bps or 1,194 Mbps

    1,194 Mbps >>>50 Mbps

    The Blu-Ray standard is 40 mb/s, thus the word virtually.

    Edit: I'll add that relative to DVD and H.264 it's not compressed too much at all.

    Blu-ray (and HD-DVD) use compression for both the video and audio payloads. Dolby TrueHD is simply a lossless format which means it does not drop data as part of the compression process. With that said, at the moment it is probably fair to say you will always get a "higher quality" source from a disc rather than any online provider.

    For a decent write-up of Blu-ray capabilities, you can look at the Wikipedia article (http://en.wikipedia.org/wiki/Blu-Ray).

    The disc creator simply has more storage (15 GB to 25 GB) to play with while online providers must be conscious of the resulting stream size and will generally at this point aim for a smaller payload size. Just to keep things confusing, a single online provider may provide different programs using different compression strategies resulting in different results depending on the program or even the season for television programs...

    To the original posters question, as unhelpful as it sounds, it is really more of a personal preference that you will have to decide for yourself. If you're planning on buying movies, you're probably going to be more critical since you are spending more money and want to get best available experience for your money. If you're planning on just renting movies and are looking for the convenience of an online source, the differences may not be as important to you.

    For me, I bought the ATV after the announcement based on the Take 2 rental features. I typically will download television shows which are purchases, but except to try it out will not "purchase" movies from any online providers at the moment. I would personally rather have the disc and the quality/extras associated with the disc. For rentals, I have rented quite a few movies from Amazon (with varying quality I might add) and will from iTunes when ATV 2.0 is released.

    You're being incredibly misleading. There's a huge discrepancy in bit rate for the two formats, which has a much greater impact on the picture than 720p vs 1080p.

    As others have said, it really depends on your TV. I have a Pioneer Plasma and you can see the difference using blu-ray.

    I use the PS3 as my dvd replacement / blu-ray player. ATV is mostly for on-line content. I tried to use the PS3 for playing on-line content, but the interface sucks for big libraries. For me, its also been a crapshoot whether it will play the same video on more than one occasion. One day a movie will play, the next, it comes up as unsupported data type.

    After having used both, I really see them as having two different uses although some would try and say they are the same.

    Bluray is absolutely FLAWLESS. But it also depends on individual titles. BluRay has a grading system, the top titles look spectacular. SOme of the lower graded titles look like basic DVD to me.


    I can't really judge how the ATV will look as i've never played any HD Content on it.

    PS3 playing video ....

    Yeah! I'm fighting the same frustrating issue. I have a Linux-based "Myth TV" box set up with a DLP projector in my basement. It works great showing movies on the projector ... but I got the idea I'd like to have access to its same library from my PS3 upstairs, so I could also watch the movies/videos on my plasma TV.

    I can't seem to get a straight answer from anybody on exactly how I should be encoding my movies to get the PS3 to play them properly without ever popping up the "unsupported data" message. I seem to have a few that it always plays just fine, but not sure exactly WHY those work and others don't.

    I've got a mix of DivX, XViD, AVI and MP4 movies (plus even a couple ISO images of full movie DVDs) and the "knoppmyth" distro of MythTV plays them all perfectly. On the PS3, serving them up over my wireless N connection, I'd say only 1 out of 5 or 6 plays properly - and some of those momentarily pause, every 10 or 15 minutes (probably due to the wi-fi connection being just a HAIR too slow to stream them effectively).

    Anyone know specific settings for a program like "VisualHub" to mass-transcode my library to work well on a PS3 (perferrably in as good a quality as possible while still compressing enough for a wi-fi connection to stream it reliably)??
